Mesa version 6.0 signifies two things:
1. A stabilization of the 5.1 development release
- 2. Implementation of the OpenGL 1.5 specification
+ 2. Implementation of the OpenGL 1.5 specification. When you query
+ glGetString(GL_VERSION) "1.5" will be returned (as long as the
+ driver supports all the required features).
Note that the Mesa major version number is incremented with the OpenGL
